Chapter 20: The Underpass

The armored bus plunged into the cavernous gloom of the financial district’s underpass.

Ren gripped the steering wheel, his newly enhanced Echolocation painting the pitch-black tunnel in sharp, pulsing wireframes of sound. Before the System arrived, he would have hyperventilated in a place like this. He remembered cowering in the university library, flinching at the sound of a dropped textbook or a senior student’s heavy footsteps. Now, the suffocating darkness felt like a warm, protective blanket.

The System had not just rewritten his DNA; it had scorched away his fear, replacing it with a hollow, gnawing furnace. He was no longer the prey.

In the rearview mirror, the Humvee’s headlights carved twin beams through the swirling ash. Chloe kept her distance, driving with the rigid caution of someone who knew death was a single missed brake pedal away.

Ren tapped the two-way radio on his shoulder.

“Headlights off,” he ordered, his voice echoing in the empty cabin.

“I won’t be able to see the road,” her voice cracked through the static, edged with panic.

“You don’t need to see the road. You just need to follow my taillights. Harsh light draws attention down here. Kill the beams.”

A second later, the tunnel plunged into absolute, crushing darkness.

Ren navigated the graveyard of abandoned commuter cars effortlessly. He steered the heavy bus around a shattered ambulance, the Echolocation feeding him a continuous stream of spatial data. The air grew thick, reeking of ozone, stagnant water, and crude oil.

Then, the floor of the tunnel began to shift.

It was a subtle movement, a ripple in the asphalt that defied physics. Ren slammed the brakes, bringing the bus to a screeching halt. The Humvee stopped a few yards behind him, the tires skidding on the slick concrete.

“What is it?” Chloe asked over the radio.

Ren did not answer. He stared at the ground ahead. The System overlay flared to life, casting a harsh blue glow across his retinas.

[Mutated Asphalt Crawler (Lvl 8)]

[Status: Ambush Mode]

[Warning: Corrosive Touch]

The city itself was coming alive. The System had taken the rats, the feral cats, and the zoo animals, twisting them into recognizable horrors. But this was an entirely different nightmare. This was a colony of subterranean insects that had secreted a shell of melted tar and concrete to camouflage themselves within the urban decay.

The pavement erupted.

Three elongated, segmented bodies burst from the roadbed, showering the armored bus in jagged chunks of asphalt. They resembled centipedes the size of subway cars, their carapaces gleaming with wet, black tar. Hundreds of scythe-like legs clicked frantically against the concrete pillars.

One of the Crawlers coiled around a support column and lunged at the bus, driving its mandibles into the reinforced steel hood. The metal shrieked, buckling under the sheer kinetic force.

Ren kicked his door open and stepped into the suffocating dark.

He didn’t bother drawing the shotgun. Buckshot would uselessly deflect off that stony, tar-thickened armor. He needed targeted, penetrating power.

“Stay in the truck!” Ren barked into the radio.

He activated Dash. Space compressed around him. He materialized directly above the Crawler’s massive head, gravity pulling him down onto the beast.

[Skill Activated: Rending Claws]

His fingers elongated into metallic talons. Driven mad by the sudden intrusion, the Crawler whipped its segmented tail, shattering the concrete pillar behind it. Ren ignored the raining debris. He plunged both hands deep into the creature’s unarmored, glowing eye sockets.

The Crawler unleashed a deafening, vibrating hiss. Acidic tar spewed from its mandibles, sizzling against Ren’s boots. His Chitin Shell passive flared instantly, hardening his skin to absorb the caustic splash.

Ren twisted his wrists, shredding the soft neural tissue behind the eyes. He anchored his boots against the beast’s skull and pulled upward with savage force, eviscerating the creature’s sensory organs.

The monster collapsed, its dozens of legs twitching in a chaotic, dying rhythm.

Ren did not pause. The second Crawler was already charging blindly, its jaws wide to snap him in half.

Ren focused his mana, drawing a deep breath of the foul tunnel air.

[Skill Activated: Psionic Scream]

The invisible shockwave collided directly with the charging Crawler. The massive insect faltered, its momentum carrying it forward as its primitive brain short-circuited. It crashed hard into the side of the armored bus, stunning itself against the heavy steel plating.

Ren sprang forward. He scaled the stunned creature’s segmented back using Wall Run, his boots finding traction on the sticky tar. He located the soft, pulsating joints between the heavy armor plates. He drove his claws into the vulnerable flesh, severing the spinal nerve cluster in one ruthless, paralyzing strike.

[Target Dead: Mutated Asphalt Crawler (Lvl 8)]

[Experience Gained: 300]

Two down. The third Crawler, witnessing the brutal execution of its kin, skittered backward. It burrowed wildly into the shattered asphalt, prioritizing survival over its next meal.

Ren let it go. Hunting a burrowing enemy in the dark wasted precious time, and he already had what he needed.

He knelt beside his second kill. The hunger was a physical ache, demanding immediate tribute. He plunged his bloody hands into the severed nerve cluster and ripped out a handful of the pale, gelatinous marrow.

He forced it down his throat. It tasted of crude oil and rusted copper.

[Gluttony Activated.]

[Consumed: Subterranean Marrow.]

[Vitality +3]

[Strength +2]

[New Passive: Corrosive Resistance (Low)]

[Description: Minor immunity to acid and toxic burns.]

Ren wiped his mouth, his breathing remarkably steady despite the carnage. He looked at his hands, watching the black talons retract into normal fingernails. He was shedding his humanity piece by piece with every meal, trading it for the raw, unadulterated power to survive.

And the terrifying truth was, he did not miss it. The old Ren was weak. The Glutton was eternal.

He keyed the radio. “Road is clear. Turn your lights back on.”

The Humvee’s high beams flared to life, illuminating the slaughtered monsters and the blood-soaked boy standing among them. Chloe stared through the windshield, her face a mask of awe and quiet horror.

Ren climbed back into the bus. He wiped his slick hands on his jacket, shifted the heavy transmission into drive, and pushed deeper into the abyss. The Stadium was waiting, and his appetite was far from satisfied.
